LEATHER-BUFFING MACHINE.

SPECIFICATION, forming part Of Letters Patent N0. 256,252, dated April11, 1882,

Application flled September 9,1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN H. STEVENS, of Lynn, county of Essex, and Stateof Massachusetts, have invented an Improvement in Leather-BuffingMachines, of which the following description, in connection with tbeac-.mcompanying drawings, is a specification.

This invention in leather-butting machines has forits objeetimprovementsin the foot and abrasive pouch to be applied thereto.

The improved foot herein described is what is known as a flexible foot,and is composed of a flexible disk having a connected flexible shanksuitably connected above the disk with the spindlewhieh revolves thefoot.

The improved abrasive pouch is composed of a circular piece of abrasiverhateriahhaving stitched to it an india rubber annulus, the latter beingadapted-to be stretched or expanded to fit over the foot and itsattached felt washers, the contraction of the said annulus retaining thepouch upon the foot.

Figure 1 represents in elevation and partial section a spindle, flexiblefoot, and abrasive pouch embodying my invention; Fig. 2, a view of thepouch turned wrong side out to show the seam uniting the circular pieceof abrasivematerialand theindia-rubberannulus, the greater portion ofthe latter being shown in 0 dotted lines. Fig 3 is a partial section ofFig. 2 on the dotted line so at, and Fig. 4 a section ot' the flexibleshank of the disk and the surrounding partof the spindle on the dottedline y y.

The spindle awill be operated as and it is adapted to be used inconnection with mechanism, substantially such as shown in my UnitedStates Patent No. 236,271, dated January 4, 1881, to which reference maybe had. In

0 that patent I employed an india-rubbcr pad or disk for the foot. Inthis, my present invention, I employa flexible disk, 1), shown ascomposed of india-rubber, the said disk having a flexible shank, bconnected with or forming part of it. This flexible shank, composed ofindia-rubber,is herein shown as connected with the spindle by beingscrewed or inserted into a socket, a forming the lower end of thespindle, the said socket being split longitudinally at two or moreplaces (see Fig. 4) to form elaso tic arms, which may be held or forcedclosely in contact with the flexible shank b by means of a ring, 0.

At the under side of the disk I) I have secured washers d e of felt. Thelower end of'55 the socket a terminates short of the top or upper sideof the flexible disk b,thus leaving the connected flexible shank free toyield between the said disk and socket. The flexible shank enables thefoot and its abrasive pouch or other covering to adapt itself to thecontour or position of the sole or other substance being buffed asfreely-as the human hand, and much more readily than when the flexibledisk is connected directly with the spindle, as in my former patentreferred to.

The pouch is herein shown as composed of a circular piece otabrasivecloth,f, and an india-rubber annulus, g, united by a line or series ofstitches, it, (see Fig. 2,) wherein the pouch is supposed to be wrongside out and the main part of the annulus g at the underv side, thelongeredge of the annulus being turned over upon the wrong side of theabrasive cloth, as shown. When this pouch is turned the narrow edges ofthe cloth and annulus beyond the seam h fallwithin the pouch,

as shown in Fig. 1.

To apply this pouch to the foot it is only necessary to stretch ordistend the annulus, place it about the foot above the disk I), as inFig. 1, and permit it to contract, the contraction of the annulusholding the pouch firmly on the foot, thus doing away with ashirringstring, such as heretofore commonly used.

I claim- 1. In a bufting-machine,the flexible diskand connected flexibleshank, combined with the washers or felt, substantially as described.

2. The spindle a, combined with and carry- 0 ing the flexible disk,having the connected flexible shank, substantially as described.

3. The spindle provided with a split socket and the ring, combined withthe disk b and its flexible shank b inserted in the said socket, 5substantially as described.

4. The pouch composed of the circular piece In testimony whereof I havesigned my name of material f and the india-rubber annulus to thisspecificationin the presence of two sub- 10 stitched thereto,substantially as described. scribing witnesses.

5. The india-rubber disk and its flexible 5 shank b and the feltwashers, combined with the abrasive pouch composed of the abrasiveWitnesses: cloth and connected india-rubber annulus 9, J 0s. P.LIVERMORE, substantially as described. I B. J. NOYES.
